` etai/irme DEVICE Application filed Maren 16, 1929. serial No. 347,598.

This invention relates to clamping devices. The object of the invention is the production of clamping devices, by means of which pipes, rods, cables, ropes andthe like can be easily and tightly clamped together. The second object of the invention is the production of devices b means of which Ji es rods and the like located at right angles to each other can be' clamped together.V The third object of the invention is the production of devices byl means of whichpipes, rods, and the like having their longitudinal axes inclined to each other can be clamped together. The fourth object of the invention is the production of clamping devices by means of which the pipes,rrods and the like of knock down structures, such as canopies and scail'olds, can be easily assembled, or dismantled.

In the accompanying drawing Fig. 1 represents a top plan View of an exempliication of a main clamping bracket of the device; Fig. 2 shows a bottom view of Fig. 1; Fig. 3 is a right hand end view of Fig. 1;

Fig. 4 represents atop plan View of a supplemental clamping bracket; Fig. 5 shows an end view of the supplemental clamping bracket; Fig. 6 represents a side elevation of an assembly of pipes and clamping bracklets for a canopy; Fig. 7 shows a right hand side view of a portion of Fig. 6; Fig. 8 shows a section of Fig. 6 on the line 8, 8; Fig. 9 is a section of Fig. 6 on the line v9, 9; Fig. 10 shows a view on a reduced scale,

similar to Fig. 4, of the supplemental clamping bracket clamping a curved pipe and Fig. 11 shows a view similar to- Fig. 2 on a reduced scale of the main clamping bracket clamping a curved pipe.

Referring to Figs. 1, 2 and 3 the main clamping bracket of the device'in this instance comprises the barrel having the outer circumferential surface 21. From one end of barrel 20 extends the clamping hook 22, and from its other end extends the internally threaded boss 23. The barrel 2()V is eut away to form an opening 26in its wall and which joins with the curved edge 27 of the hook 22. A clamping screw 3() having its longitudinal axis inclined to the longitudinal aXis of the barrel 20 is in threaded engagement with. the internal thread of the boss 23. A pair of screws 31 are in threaded Aengagement with the barrel 20. A pipe 35`is located in the opening of the barrel 20 and a second pipe 36 at right angles to the pipe 35 bears on the latter and on the inner curved edge 27 vof the hook-22. One end of the clamping screw bears against the pipe 36, and thereby both the pipes and 36 are securely and detachably clamped in place. The screws 31 are used to hold the main clamping bracket having Ythe barrel 20 in position on the-pipe 35 during theassembling of a structure like a canopy or scaffold and before the pipe 36 is clampedV in position.

Referring to Fies. 4 `and 5 the supple-y plugrom to 36 constitutes the posts of the canopy: A Y

horizontal member of the canopy is indicated by the pipe 35a, similar to 35. A pair of the main clamping brackets oppositely positioned connect the horizontal member 35a and the posts 36a and-361. The'post 36a forms a bow 36c at its upper portion and the post 36" forms a bow 36d at its upper portion. Each of the main clamping brackets for the canopy consists of the barrel 20, the hook 22, the clamping screw 30 and its other appurtenances as already described.

The post 16ahas connected thereto below its main clamping bracket, one of the supplemental clamping brackets indicated with its barrel having the hinged members 41, 42, the plug members 44, 45, the hinge pin 48 and other appurtenances as already described. To the plug members 44 and 45 is clamped one of the main clamping brackets shown with its barrel 20, the clamping hook 22, the boss 23, the clamping screw and other appurtenances already described. A pipe h similar to 35 is clamped tothe barrel 20 of the lattermain clamping bracket and its longitudinal axis is inclined to the pipe 35a as clearly shown in Fig. 6. The

Y inclination of the pipe 35h ispobtained by its hinged member 42, the hinge pin 48, the

plug member and other appurtenances as already described.

Referring to Fig. 1l, the curved pipe 50` has clamped thereto the main clamping bracket, indicated with its Vbarrel 20, the

l `hook 22, the clamping screw 30 andits other appurtenances as already described. `The pipe 35 is supported in the barrel 20.

invention and the present exemplifieation is ito be taken as illustrative and not limitative thereof.

Having described our invention What We desire to secure by Letters'Patent and claim is' l. The combination Viii a clamping bracket 1 of a barrel having an opening in the Wall,

said barrel adapted to support a pipe, a clamping hook extending .frompthe barrel, said hook adapted to support a second pipe at right angles to the first pipe,rthe second pipe located over the opening in said barrel and bearing on the first pipe, an internally threaded boss extending Yfrom the barrel and a clamping screw with its longitudinal axis inclined to the. longitudinal axis of the barrel in threaded engagement with said boss and one oi its ends adapted to bear against said second pipe to clamp both of said pipes to 'said clamping bracket.

l 2. The combination of a main clamping bracket, comprising a barrel having an .opening formed in its Wall, a hook extending i from the barrel, said barrel adapted to support a pipe, a supplemental clamping bracket functioning With the main clamping bracket, the supplemental clamping bracket n comprising a pair of hinged members, a plug member extending from each hinged member, said hinged members adapted Vto support and clamp a second pipe, said plug members located under the hook `ot the main clamping bracket and bearing on said iirst Y i pipe and a clamping screw 'in the main Various modifications may be made in the clamping bracket adapted to clamp said plug members in various angular positions,

and thereby locate the first pipe with its longitudinal axis inclined in various angles tothe longitudinal axis of the second pipe.
